MR arthrography of the hip.

Hip arthroscopy can be performed on an outpatient basis and has a shorter period of rehabilitation than is necessary after an open hip arthrotomy or reconstruction. The procedure makes possible accurate diagnosis and treatment of acetabular labral tears and loose bodies. Further advancements are necessary in optical equipment; manual and motorized equipment; and simple, reliable traction devices specific for this procedure. Refinements in patient selection and the increased availability of specific outcome data will help to define the role of hip arthroscopy in orthopedic practice.
